PADLOCK.

SPECIFICATION forming part of Letters Patent No. 585,594, dated June 29, 1897.

Application filed December 24, 1896. Serial No. 616,878. (No model.)

To all whom it may concern:

Be it known that LWOODBURY D. ROBERTS, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Lock, of which the following is a specification.

My invention is in the nature of an improved hasp or pad lock, and more particu-` ing the jaws to their closed position.

In `the construction of the lock disclosed by the patent referred to the several parts are so arranged that a double movement of the endwise-movable jaw is required to bring it to a locked positionwil. e., it must be first swung to a closed position to engage its fellow member and then endwise to admit the looking devices to operate to hold the jaws to a locked position, such independent movements, owing to the arrangement of the several parts, requiring the manipulation ofthe lock by both hands.

The primary object of this invention is to provide a lock having a jaw held for endwise movement on its fellow member, which when swung to its closed position will receive its endwise movement by engaging with its fellow member, whereby the lockcan be readily closed by one hand, the endwise movement being effected, as it were, by forcing the pivoted jaw against its fellow member.

The present invention also seeks to simplify the construction of the several parts of my former lock and especially to provide a very simple and easily-constructed lock device for holding the jaws locked which cannot be picked.

Furthermore, this invention has for its object to provide a simple and durable spring device for throwing the pivoted jaw open when the lock devices are key-released.

With other objects in view, which will hereinafter appear, the invention consists in the peculiar construction and novel combination of the several parts, all of which will be iirst described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure l is a plan view of myiinproved lock, the jaws being in a locked position. Fig. 2 is a similar view of the same, the jaws being open. Fig. 3 is a plan view, the cap-plate being removed and the pivoted jaw, being unlocked, swung in and about to engage its fellow jaw member. Fig. et is .a detail section taken on the line 4 al. of Fig. 3. Fig. 5 is a similar view, the parts being shown in their unlocked position. Fig. 6 is a plan view, on an enlarged scale, of the pivoted ends of the jaws, the lock, and the spring devices, the cap-plate being indicated in dotted lines. Fig. 7 is a detail view of the pivoted-jaw-opening spring. Fig. 8 is a view of the cap-plate, and Fig. 9 is a View of the tumbler or spring detent hereinafter referred to. Fig. lO is a view of one form of key used with my lock.

The present form of lock comprises two jaws or members A and B,whch have substantially the shape shown, or may be of any other de# sired shape, so far as relates to the body portion of the jaws. In every instance, however, the ends of 'the jaws are adapted to interlock. The pivot ends of the jaws are provided with ears or hinge portions O and C', through which passes a pivot or rivet pin l). The opening E in the ear portion C and in the cap-plate F is circular, while the opening E in the ear C of the pivoted jaw is elongated, with its major axis at an angle to the line centrally dividing the heads of the jaws A and B, the purpose of such elongation being to permit the hook ends of the jaws A and B to clear each other and to admit of a bodily endwise movement of the pi voted jaw on the Xed jaw, for a purpose presently explained.

In my patented lock hereinbefore referred to the free ends ofthe jaws terminate in arrow or spear shaped heads, which are adapted to interlock when such pivoted jawis moved bodily endwise by hand.

In the present form the jaws also have spear or arrow shaped ends A' B, which, however, terminate in cut-off or abrupt p ortionsI a b', cut at an angle or bevel substantially at an IOO angle parallel with the major axis of the elongated pivot-opening in the ear C, the undercut or lock portion d2 and b2 of such heads being also beveled or angled, as shown. The Object in thus constructing the lock ends of the jaw is twofold. First, it provides a means whereby the pivoted jaw B is caused to move bodily endwise on its pivot as it is closed up against its fellow A. This operation will be clearly understood by referring to Fig. 3. Thus when the jaw B is swung to a closed position, which is readily effected by one hand, until its bevel end a b and a2 b2 contact, and further pressure applied on the jaw B in the direction indicated by the arrow l0, the ineline or beveled ends of the jaws will cause the jaw B as it is thus further closed in to move bodily endwise in the direction indicated by the arrow 20, it being obvious that as the inclined faces or angles of the lock portions are in a plane parallel with the elonbeing moved endwise.

gated pivotal opening such jaw will readily move up in a position to be held locked by the locking devices presently referred to, such construction of parts providing, as -it were, practically an automatic means for imparting the bodily endwise movement to the pivoted jaw. Secondly, as the lock-necks or undercut portionsare disposed at an angle to the direct central or pull line of the lock the lock strength of the jaws is thereby materiallyincreased, as the same cannot be readily pulled apart by any 4unusual strain thereon.

To lock the jaws when they are closed together, I provide the head a3 of the member A with a recess or socket G, in which is held a slide-bolt I-I, forced normally outward by a spring h, so its front end will engage a shoulder I on the ear G, as clearly 'shown in Fig. 6. The bolt H has a cut-out or socket portion h", in which is held a tumbler or detent J, the 1 upper face of which is beveled in the direction of the keyeslot K, which face is normally held ina plane above the top of the bolt II While I have shown the lock formed with j ways for a key having but two wards m m', it is obvious that a greater number of ways may be provided to receive keys having ang In all instances,

increased number of wards. however, one of the wards of the key is made long enough to pass through the lock-head of the jaws A `and beveled, as shown at m2, to i engage the beveled detent J. The cap-plate L has a pendent ward Z2, which when the parts are in their locked position, as shown in Fig. 5, projects down at the rear end of the detent :l J and forms a lock-stop to prevent the bolt While the ward Z2 forms a lock-stop, it also forms an effectual means to prevent picking the lock by a wire or other device. Thus should a wire be inserted through the keyway at the rear of the ward Z2 to engage the incline or key-engaging portion 77,2' of the bolt such ward Z2 will prevent the bolt from movingv endwise, it also forming an abutment to prevent a wire or other implement from being moved against the portion h2, which might be entered in the keyway to depress the detent J.

So far as described it will be readily seen that when the proper key is inserted its ward m will first depress the detent J, after which its ward m will engage the portion h2 of the bolt and force it endwise out of a locked engagement with the ear C', the detent J during such interlocked position of the bolt being held down in its recessses by the ward Z2, as clearly shown in Fig. 4, it rising up again in front of such ward Z2 as soon as the bolt I-I moves back to its locking position.

In the present invention I have also provided simpliiied and more effective spring devices for throwing open the jaw B when unlocked. By referring more particularly to Figs. 6 and 7 it will be seen that the ear C is provided with a recess c2, in the outer end of which is a socket c3 to receive the spiral end n of a bow-spring wire N, which bows about the pivot of the jaws and terminates in an eye or hook end n to receive a pendent lug Z5 on the cap-plate, such lug being so arranged that when the cap-plate is placed in position a tension will be imparted to the said spring which will serve to Vthrow the jaw B open when released, the spring N having its end n2 iix'edly connected to the ear C', as shown.

By providing a spring device arranged as shown it is obvious that when the jaw is un-` locked the spring as it expands will as it throws such jaw open also force it bodily endwise outward at the same time. Y Having thus described my invention, what I claim, and desire to secure by Letters Patent, is- I p l. In a padlock, a jaw pivoted at one of its ends to its fellow member, and at its opposite end hooked to its fellow member, said jaw having bodily endwise movement to disengage its hook before swinging open on its pivot, such jaws having their hook ends provided with engaging members inclined at a plane at an angle to a line drawn vertically through the pivot and the hin gedends, whereby a lateral compression of the jaws will cause the swinging jaw to move endwise on its pivot as its hook end locks with its mate as speciiied.

2. In a lock as described, the combination of the jaws pivotally joined atene vend and having interlocking means at the other end, one of said jaws having an endwise movement on its mate, a cap-plate secured to 'such mate having a pendent lug, a bow-spring secured at one end to the endwise-movable jaw and having its other end held in a hooked yengagement with the cap-lug, and means for holding the jaws to a locked engagement substant-iallyvas shown and described.
